This is with an onboard CS4614 audio chip. The board also has an onboard Adaptec aic7899 Ultra160 SCSI adapter that shares irq5 with the sound chip: [hbo: ~] dmesg | grep 'pcm\|csa\|ahc' ahc0: <Adaptec aic7899 Ultra160 SCSI adapter> port 0xec00-0xecff mem 0xfafff000-0xfaffffff irq 5 at device 10.0 on pci3 ahc0: aic7899 Wide Channel A, SCSI Id=7, 16/255 SCBs ahc1: <Adaptec aic7899 Ultra160 SCSI adapter> port 0xe800-0xe8ff mem 0xfaffe000-0xfaffefff irq 11 at device 10.1 on pci3 ahc1: aic7899 Wide Channel B, SCSI Id=7, 16/255 SCBs csa0: <Crystal Semiconductor CS4614/4622/4624 Audio accelerator/4280 Audio controller> mem 0xfae00000-0xfaefffff,0xfaffe000-0xfaffefff irq 5 at device 6.0 on pci2 pcm0: <CS461x PCM Audio> on csa0 Sound output works fine after rebooting, but after a few hours of playback, sound starts to get choppy and hissing. Nothing short of a reboot seems to fix this. Also, if I disable the ahc controller in the BIOS (there are no devices connected to it), I get messed up sound output right from the start. I suspect there is some problem with the pcm/csa driver and shared interrupts. Please let me know if you require more information. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
